How do I choose a server engine

Hi all.

We want to make a complex game like Clash Royal. To save time, we want to use existing server engine for features like user management, leader-board, messages, and other basic game features. We are interested in Gamesparks (it has Construct2 demo, but it is expensive if we have high MAU). Is there any other server engine choices to easily work with Construct2?

Thank you!

As robust as gamespark, from what ive researched, you can try playfab.

Actually mb, i dunno if they have a plugin for C2.

thank you!
